Google Maps is a must have on Android. This is one of the apps that makes Android stand out from iOS. Navigation is free, as it should be. It's a shame navigation isn't in the iPhone version of Google Maps. I don't know if Apple or Google made that decision, but it wasn't a good one. Hopefully, for iPhone users, this will be rectified in the future. However, I don't really think it will happen. Overall, Google Maps is still the best mobile map app on any platform. Nothing does it as well. I would like to see the satellite images updated more frequently, but that would be difficult.
